A clipper system moves across the Great Lakes today and should trigger some snow in Ohio as we move through midday and afternoon. Snows can continue overnight tonight and may take into early tomorrow to finally exit the state. Snows are not all that impressive at this time, but we are expecting a coating to 2 inches over about 80% of the state. The good news is that we don’t think winds will be much of a factor during the event, so significant blowing and drifting is not likely. Most of the state will be done with snow by midnight to 3 AM tomorrow, but far southern and southeast areas may take through sunrise tomorrow to get through it. The map above shows snow totals through just after midnight tonight.
Behind this clipper comes a reinforcing shot of cold air that holds through most of the rest of the week. We can see some subzero temps tomorrow night into Wednesday morning as skies clear, and we see highs doing no better than mid-teens to mid-20s through Thursday. Friday we may get back closer to normal for this time of year. The week will be dry, and we do expect sunshine to be a big player, much like we saw yesterday. Sunny and cold will describe most of this week.
Strong southwest winds bring moderating temps back for the weekend. We go above normal Saturday, and stay there Sunday as winds strengthen ahead of our next front. With the moderation, we won’t rule out a few scattered showers in NW and west central parts of the state late Saturday night through midday Sunday. Those will be limited to a few hundredth to a tenth or two and coverage of 30%. The front mentioned above does not arrive in Ohio until Monday early morning. Rains continue through most of Monday and can bring rain totals of .25”-.75” over 100%. The map above is a snapshot of action from next Monday morning.
Temps cool slightly behind that front for early next week, but we do not see cold arctic air returning. Instead, temps stay near normal for most of next week. South winds are back at midweek, suggesting that another strong system is in the works out in the plains. Indeed, in the extended 11-16 day period we see a massive system coming together in the 4 corners region late Friday, the 26th, and then it slowly churns eastward. This significant storm looks to move into our region around the 28th, and will have liquid equivalent precipitation potential of half to 1.5”. Currently, the track of the heaviest action is well south of us, crossing the Deep South, but a system like this needs to be watched as it evolves. Behind it we likely see cold arctic high pressure returning for the finish of the month and start of February. The cold air should come in stages…the initial push behind the front for the 29th and 30th, and then a colder shot behind a clipper we think could emerge around the 31st into the 1st.
